Name: "kill",
|
|
Usage: "kill sends the specified signal (default: SIGTERM) to the container's init process",
|
|
ArgsUsage: `<container-id> [signal]
|
|
|
|
Where "<container-id>" is the name for the instance of the container and
|
|
"[signal]" is the signal to be sent to the init process.
|
|
|
|
EXAMPLE:
|
|
For example, if the container id is "ubuntu01" the following will send a "KILL"
|
|
signal to the init process of the "ubuntu01" container:
|
|
|
|
# runhcs kill ubuntu01 KILL`,
